I am developing an application using telit module GE 864 gps, with the EVK2 evaluation kit. Being a software developer, I need a little help understanding the power supply for the motherboard. Power supply inputs on the motherboard are following:
-5-40 V power jack
-3.8 V wire
-5-40 V wire
-battery and charger
My questions are:
Does choosing of the power supply depends on the functionality of the module or can I choose whatever I want?
What is the difference between fixed DC and variable DC considering functionality?
